Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medium and thick plates, in particular to a rotatable medium and thick plate roller changing trolley hook head device. Background Art
[0002] Medium and thick plate production lines are generally equipped with two four-roller reversible rolling mills for rough rolling and finishing rolling. In order to ensure product quality, it is generally required to change the rolls once a day. The replaced rolls need to be hoisted to the grinding roll room in time for re-grinding to remove the surface hardened layer, and then assembled for use on the machine. To ensure the normal operation of the production line, the mill is using a pair of rolls and a spare pair of rolls next to the machine. After the rolls are changed, the old rolls need to be hoisted out and the new rolls need to be prepared on the roll changing track. Four rolls need to be hoisted back and forth.
[0003] Since the hook head of the roller-changing trolley is designed to be fixed, the end of the working roller falls on the hook head of the trolley and is connected with the hook head of the trolley. The wire rope of the hanging roller cannot be moved out from the side. Two people are required to remove one end of the wire rope from the crane hook, and pass it through the bottom of the connection between the hook head of the trolley and the end of the working roller, and re-hook it on the crane hook. Since the single weight of the roller is about 30 tons, a large-sized wire rope with a diameter of 38mm and a length of 12000mm is used to ensure the safety of lifting. Due to the heavy weight of the wire rope and the complex environment of the operating area, it takes 10 minutes for two operators to complete a wire rope threading. This reduces the operating efficiency on the one hand, and on the other hand, removing and hanging the wire rope on the crane hook brings safety hazards to the on-site operators.

BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0014] Description of the accompanying drawings: lower panel 1, bottom plate 2, upper panel 3, swivel hook 4, hook block 5, rotating shaft 6, positioning pin 7. DETAILED DESCRIPTION
[0015] See also Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: it includes a lower panel 1, a bottom plate 2, an upper panel 3, a swivel hook 4, a hook block 5, and a rotating shaft 6. The lower panel 1 and the upper panel 3 are welded to one end of the bottom plate 2, and a rotating shaft 6 is penetrated through the lower panel 1 and the upper panel 3. The swivel hook 4 is rotatably connected to the lower panel 1 and the upper panel 3 through the rotating shaft 6, and a hook block 5 is installed at one end of the front end of the swivel hook 4.
[0016] More specifically, positioning pins 7 are provided on the lower panel 1 and the upper panel 3, and the positioning pins 7 are located at the front end of the rotating shaft 6. The positioning pins 7 can ensure that the rotating hook head 4 and the roller are parallel to each other, ensuring that the working roller is normally hung.
[0017] More specifically, the lower panel 1 and the upper panel 3 are respectively welded to the upper and lower sides of the end surface of the bottom plate 2. The lower panel 1 and the upper panel 3 are used to limit and fix the rotating hook 4 thereof.
[0018] To be more specific, both the lower panel 1 and the upper panel 3 are provided with shaft holes for installing and fixing the rotating shaft 6 and positioning pin holes for installing the positioning pins 7 .
[0019] More specifically, the lower panel 1, the bottom plate 2, the upper panel 3, the rotating shaft 6 and the positioning pin 7 are all made of 42CrMo material. 42CrMo is a high-quality alloy structural steel with high strength and toughness, high fatigue limit and multiple impact resistance, and good low-temperature impact toughness.
[0020] The working principle of the utility model is as follows: when the operator is hoisting the roller, the positioning pin 7 is first taken out, and then the rotatable hook head 4 is rotated, so that the rotatable hook head 4 is rotated based on the lower panel 1 and the upper panel 3, the rotatable hook head 4 and the hook head block 5 are rotated to the side, and then the wire rope is taken out from the end of the roller, which can completely solve the problem of frequent threading of the wire rope during the roller preparation process.
